or the like, and has for one of its objects to simplify and improve the constructiona and increase the efficiency and utility of devices of this character; 1

Another object of the invention is to pro- 1 vide a device of; this character adapted to bedetachably coupled to a cultivator or like implement in position to operate without interfering withfthe ordinaryjoperations of the cultivator, or so that theichopping action and cultivator action may be conducted simultaneously.

WVith these and otherobjects inview, the invention consists in certain novel: features of construction as hereafter shown and described, and then specifically pointed out in the claims, and inithe drawings illustrative: of the preferred embodiment f the inven: tion, Figure 1 is a side elevation partly in sectionof the improved device mounted upon; a conventional. cultivator frame. Fig.2is a. section on the line 22 of Fig. 1,3looking; in. the direct-ion: of the arrow. Fig, 311s an: enlarged and detached perspective view of the chopper device. 1

Corresponding and like partsare referred to in the following descriptionand indicated, in all the views of the accompanying drawings by the same referencecharacters.

The improved apparatus may be applied without material structural changes to the various forms of eultivators inuse and for the purpose of illustrationds shown applied to a conventional cultivator 1 including an, elevated axle mechanism 10 having the usual bearing wheels one of which is shown at 12, an arched framel lin advance of the axle frame andcoupledrigidly thereto and likewise tothe supporting members of the tongue 16. The cultivator beams 17 are connected to the arched frame 14: as shown, at 18, and the beams will have the usual, hoes notshowirfl i Extendingbeneath the members 10-44 is an oblong frame comprising side members Specification of Letters Patent.

20-21., a rear member 22, and a frontimember 23.3 Bracketsone of which is shown at are rig dly connected to the vertical por-;

tions ofthe arched supportingframe 14 and pivoted at 26-2?: to the frame 1 members 20-21, whereby the oblongframe is swing ingly connected to the arched supporting frame. The side members 20-21 of; the

frame extend forwardly of the transverse member23 and terminate in bearings 284-29 through which? a shaft 30 is mounted for;

rotation.

Mounted for rotation in bearings 4H5,

is a shaft 46, and connected to the shaft, is

a bevel pinion 47 engaging with aibevel gear 41 on the shafti30; The shaft 46 is provided with stop collars 48%9 which limit IltS longitudinal movement, and the shaft is likewise provided with a crank 50 and a balancewheel 51. a

Mounted to swing ;upon the crank 50 is a standard or bar 57 which is coupled to the crank T by a cap 58 and provided at one end with a plurality of apertures 59 spaced apart. Pivoted at 60 tothe opposite end 10f the bar 57,1 is a standardmember 61 forked at one endto bear uponopposite sidesof the memberi57 and with notches 62 nearthe and projecting at either side, the bolt having a clamp nut to enable the forked portions of the memberfil to be clamped to the member 57. By this means whenthe member 61 is disposed in longitudinal alinementwith the member57,the notches 62 will engage over the bolt 63 andzpositively limit the imovement of the member 61 inone direction, and

yield-ably limit the movement in the oppoe site direction as hereafter explained. A cutting blade (55 is connected to the lower end of the member 61 and forms the chopping member ofthc improved device. Rising from one ofthe side members, for instance the member 20,,isa standard 66, the standard being coupled by a rod 67 to one of the apertures 59 of the member 57. By this arrangement the upper end of the member 57 is maintained inflfixed relations to the frame face during its forward stroke and to move upwardly and laterally above the ground at the return stroke. By providing a plurality which are severedby the chopper blade 65, may be thrownto one side, or the ground, adjacent to the severed 'pl'ants, cultivated member 61 With sufficient firmness to resist its displacementfrom the bolt under ordinary conditions, or When chopping the;

stalks of the plants, but in event of meeting with abnormal resistance, or an obstruction 1 v vhic h Wouldbe liable to injure or break the cutter-- members, the .member 61 Will yield and-release the notches 62 fromthe bolt 63 thus prevent breakage of the parts.

The member 57 is provided With a socket 68 and StSOIBW 69 'to receive and support an L-s'h'aped standard 70 having raker teeth 71 at'itsfr'ee. end. By this meansfthe plants or similarly treated at the same time 'that the cuttingaction is produced.

, Mounted uponthe frame member 10, is a notched segment 72 over which a lever 73 operates and isprovided With a spring pawl 74Tengag'ing ithg'the notches of the segment. The lever 73 is provided With a lat-' eral arm 75, While the framemembers 20-21 areconnected by a bail? 6 from which a rod 77 leads to the arm 75. By this simple means it Will be obvious "that the oblong frame may be adjusted vertically or [caused to swing uponitspivots 26 27 and thus correspondingly adjust the shaft 46 and its at tachments vertically, or elevate the frame and its attachments bodily from the ground when not required.

WVith the device thus constructed, it Will be obvious that the surplus plants may be readily chopped out at certain predetermined intervals as the cultivators move forward, While at the same time the ground between the rows of plants may be culti- Copies ofthis patent may be obtained for five, cents each, by-add'ressing vated simultaneously Witlr'the' chopping op erations. l

The improved apparatus is simple in. con

struction, canf be inexpensively manufac tu'rcd, and applied Without material structural changes to cultivatorframes of various forms.
